v Witliiari air tube17 which leads thereinto and a suitable needle valve 18 controls the oil through the port 13. As the piston rises a considerable vacuum is formed when it reaches. a pointadjacentits' complete inward movement, at whichtime the ports 13 and 14 are in registry so that a small jet of oil is sucked through the ports 13 and 14 into the tube 15 and as the vacuum in the tube 15 is only'momentary, the 'oil thus drawn thereinto will be discharged into the cup 11, 'from whence it passes around the bearing on the piston pin and throughthe channel 10 to the crank bearing.

Mounted in'a recess 18? which communicates through a'port 19 with the interior of the cylinder at certain times is the piston or plunger 20 having a guide rod 21 extending through a' packingnut or gland 22. This port 19 is unmasked when the piston reaches a point adjacent its lowest the exhaust may force the plunger outwardlyand thereby gain access to the outlet port23. The plunger rod 21 in its [outward movement contacts with the lower end of a valve lever 24 which is pivoted upon a bracket 25 and has adjustably secured to its upper 'end the exhaust valve rod 26 to the inner end of which is connected the exhaust valve 27 controlling the main exhaust port 28. plunger 20, thelower end of the valve rod '24 will be drawn outwardly and the upper .end will be drawn inwardly against the tension of a spiral spring 29 so as to unseat the main exhaust valve 27 and thus unmask the port 28 so that upon the next upward stroke of the piston the burnt gases therein will have a free and unobstructed exit.

As the action of the exhaust on the plunger 20 is only momentary it is necessary that position so that' and is provided with a single ratchet tooth 31. The pawl is connected to an operating The operating lever is pivoted horizontally upon the lower part of the casing and has its inner end connected with a spiral spring 34 carried by the casing and-adapted to' normally raise the link 33 and 32 upon which is journaled a roller 35 adapt- .When the exhaust depress the outer end of the lever miss an explosion,

the lower end of the the ratchet tooth 31 operates the plunger lever 24 will snap over and thus hold the valve 27 ofi its seat independent of any action on the part of the plunger. As the piston rises in the exhaust stroke, the cam face 36 will act upon the roller to raise one end of the lever'32 and draw downwardly upon the link 33 thus releasing the pawl from the lever 24 and permitting the spring 29 to positively seat the valve 27 and thus. permit the piston on its next downward stroke to draw in a predetermined quantity of gas as will'hereinafter be described. It will be noticed that the lever 24 is only operated and held in operative position when the exhaust from a direct explosion occurs. Should the engine the piston on its down ward movement would tend to neutralize tating in the casting by the casting the pressure in the combustionchamber .37

so that the plunger 20 would not be operated, therefore on the'next upward stroke of the piston an explosion would occur if the ignition mechanism were actuated.

lVhile "the ordinary type of sparking mechanism may be employed to ignite the charge in the combustion chamber, I prefer to dispense with the same on account-of the complicated nature of make and break devices and the inaccuracy and necessary fine adjustment of reducing gears and timers used in jump spark arrangements. To take their place I prefer to use an extremely simple ignition device which will now be, described. Mounted upon the casing is a suitable casting 38 having ports 39 and 40, therein which register with ports 41 and 42 in the casing. The port 41 is formed in the casing so as to be in communication with the combustion chamber 37 at all times and leads through the port 39 to a channeled plug 43 which is adjustably mounted within by means of a nut 44. This nut forces the plug 43 outwardly into engagcl ment with a porcelain tube 45 whose other l end is seated in a packed socket 46 in the valve cylinder 47 supported upon the casting 38 and having a needle valve 48 to control the channel between the tube and the port 40. Thejplug 43 is prevented. from 1 rneans of a plug 49 which is provided with a slot 50 adapted to receive a rib 51 on the plug.

The piston 8 has formed in its side wall an expansion chamber 52 which is in communication with the port 4'2 at certain times through'an outlet 53. The operation of the ignition device is as follows: During the exhaust and intake strokes the tube45 and the parts which lead thereto remain full. of burnt gases. Upon the compression stroke these burnt gases are forced by the live gases 1 through the ports 40-42 and 4l-39 toward the tube 45. The capacity of the tube and l the ports'leading thereto is such however, l

that no live gases will get into the tube during the compression stroke. .At the end of the compression stroke the port 42 registers with the port 53 and the expansion chamber 52 so that the burnt gases in the combustion chamber enter into said expansion chamber and the live gases thereby gain access to the tube thus producing-an explosion. I

The cooling feature of the engine may be described as follows: A port 54 is formed in the casing 1 below the lowermost position of the head of the piston 8 and below the lower edge of the piston when itis in its upper position. hen this port is unmasked by the piston in its instroke, a considerable vacu-' um is in the casing and as a consequence a quantity of air is drawn into the casing and. compressed upon the down stroke of the piston This air circulates around in .thc casing until a portformed in the piston'registers with the port 54 in the casing at which time most of the air in the casing will be expelled under compression, having first thoroughly impinged against the head of the piston 8, thus cooling the same. A cor-- tain quantity of the air thus compressed in the casing passes through a port 56 and engages a diaphragm 57 secured in a casing 58 which is in communication with the water supply through a pipe 59. The casing is hollowed out. so as to form a compartment 60 to one side of the diaphragn'i which reccives the water through a port (ll controlled by a ball check 62. A similar port ()3 controlled by a ball check ()4 leads into the water jacket whereby drawn into the casing 58 by the diaphragm will be circulated around the engine. \Vhcn the piston rises upon its instrokc, a vacuum is formed in the casing which moves the diaphragm toone side or the compartment 60 and sucksin water through the ball check 62. Upon the down stroke of the p'iston a pressure is formed in the casing which throws the diaphragm to the opposite side of the compartment 60 and expels the water in said compartment through the port ()3 past the ball check 64 into the water jacket 65, the ball check 62 at this time being seated and preventing the water from flowing into the supply pipe The intake of the air in the port 54 andthe escape of the same through the port prevents too. violent; compression and vacuum so that the' diathe water which is" phragm 57 is operated evenly and without I per end of the casing 68 and an adjustable collar 73' carriedupon thestem,v A cha n tween the baflie plate a combustible mixture. returns on ts lnstroke,

neled plug communicates with a mixing chamber 74 which is in turn in communication with an air inlet port-f75. This air inlet port is of sufiicient' size to permit the requisite quantity of air tiiibe admitted to the mixing chamber 74 and has slidably mounted therein a baffle plate, 76 which is rigidly mounted upon the'pump plunger 77. guided in its movement by an apertured inlet plate 78 at. one

The pump plunger is end and inder 7 9 casing 68. This plunger with its rigid bafiie plate isheld in raised position by a spiral spring 80 which surrounds the plunger be and the pump cylinder, The fuel inlet port is shown at 81 and is adapted to communicate with a lateral extension 82 of the pump cylinder. through a port 83 which is controlled by a springpressed valve 84. The inlet port for the fuel from theextension 82 to the mixing chamber is controlled by a springpressed valve 85 and a foraniinous cage or cylinder 86 .is arranged on opposite sides of'the valve 85 which receives the fuel and spreads it out into a film so as to be readily vaporized by the incoming air.

Recapitulation: In the drawings the piston in both instances is shown at the end of its instroke. If We now turn the flywheel in either direction, the ducing a vacuum above it which draws down upon the valve/ and sucks a predetermined quantity of air through theports in the plate 78. This air impinging against the battle plate 6 carries it downwardly against at its opposite end by the pump cylthe action of the spring and operates the pump plunger within the pump cylinder, thus injecting the fuel past thevalve onto the foraminous cylinder 86. Theair entering the mixing chamber immediatelyafterward vaporizes the fuel and produces the mixture is compressed in the combustion chamber and when the crankreaches the dead centerline the charge is ignited by the ignition tube as hereinbefore described. The piston then descends, driven by the expansion of the burnt gases and at the end of the outstroke the port 19 is unmasked. The exhaust forces the plunger 20 outwardly and carries the lever 24 with it so that its lower end is snapped.

over the ratchet teeth 31 and the valve 27 is forced to open position. Upon the exhaust stroke of the cylinder-,the remaining gases are forced out of the port 28.' Toward the which is formed integrally with the piston will descend pro- 7 tube and convey it to the combination with a cylinder,

When the piston end of the exhaust stroke, the eccentric 36 actsupon the lever 32 to withdrawthe pawl 30 from the end of the lever 24 and thus releases the valve 27 which is returned to closed position by the spring 29. The piston then moves, outwardly drawing in a new charge and thus continuing the cycle. During the instroke ofthe piston, a vacuum is produced in the crank case and toward the end of the instroke, the air inlet port 54 is unmasked so as to allow a predetermined quantity of air toenter which is compressed during the outstroke until the port 55 registers with the port 54 when the air is ex; pell-ed after thoroughly cooling the piston head, This air also acts upon the diaphragm 157 to cause the circulationof water through the water jacket as heretofore described. Having thus described the invention, what is claimed is,
